Worth the trip to Freycinet to see the bays and walk around this gorgeous and fun park. The time estimated provided are fairly accurate. The walk to Wineglass Bay lookout, thought not technically difficult, does go through a pretty significant elevation change in a short time, involving both steep slopes and plenty of steps. I don't know the exact number of steps involved, but there were enough (in the hundreds I believe) that when I saw that the hike to the beach involved another 1000 steps, I chose to just stick to the Wineglass Bay loop (given a bad knee).
The 40ish minute hike is a loop, so you rarely see other hikers (until the lookout). The lookout itself is gorgeous and well made. It's a fairly long platform; you keep going, expecting it to end, and it keeps offering new vantage points.
The journey back is a bit less scenic and, unless I missed something, offers less rest spots than the way up (I only recall seeing one bench on the way down, that also offers one of the best vantage points of the hike).
All around, it's a great hike and should be doable by most people. There's plenty of spots to rest, it's about 20ish mins both ways (so you're only ever 20ish mins away from the parking if you can't continue), and the views are amazing.
